got a cylinder seal groove set up for a 1.00 inch shaft, is this u-seal the right size or am i gonna be fightin it
Question by: Ricky G on Apr 12, 2025, 9:43 PM
The key dimensions are a 1.00 inch ID and a 1.375 inch OD, with a 0.1875 inch cross section and about 0.19 inch height. If your setup is truly built around a 1.00 inch shaft size, the 1.00 inch ID is the matching number, and the other dimensions need to line up with your groove and bore.

Does this seal hold up at high pressures, or is it more of a light-duty part?
Question by: Harold G on Nov 8, 2025, 7:09 PM
Rated up to 6,000 PSI, it handles serious hydraulic pressure without issue. The polyurethane construction also gives it solid wear resistance, so it's not going to break down fast under load. For most heavy-duty hydraulic applications, that pressure range covers just about everything you'd run into.

What's the deal with the beveled lip? How's that help it seal?
Question by: Melvin H on Oct 18, 2025, 8:29 PM
The beveled lip is designed to provide superior film breaking, which basically means it helps the seal maintain contact and prevent leaks, especially under tough conditions.
